Week nineteen, and a flutter.

You're sitting still for once, maybe on the couch at the end of a long day, and there it is. A tiny flicker, low in your belly, so light you almost wonder if you imagined it. Then it happens again. Somewhere in there, your baby just said hello.

This stretch of pregnancy is full of moments like that. Not the big day yet, but a run of small, bright firsts that make it all feel real.

The first flutter

Feeling your baby move for the first time has a lovely old name: quickening. It usually arrives somewhere around 16 to 20 weeks, though some moms feel it a little sooner or a little later.

Your baby has actually been moving since around 12 weeks. She's just been too small for you to notice.

If this is your first pregnancy, don't be surprised if you're closer to 20 weeks before you're sure. Moms who have been pregnant before often notice it by about 16 weeks, because they know what they're waiting for. Most people feel some movement by 20 to 24 weeks.

What it feels like

Not a kick, at least not yet. Moms describe it as flutters, bubbles or tiny pulses. Some say it's like butterflies, a gentle tap, a popping bubble or a light roll. You might first catch it in a quiet moment, and it's worth stopping to smile about.

Over the coming weeks those whispers grow. By the third trimester, her movements become stronger and sharper, and you'll get to know her rhythms well.

Who's in there, right now

At 19 weeks, your baby's growth slows a little, and something sweet happens: a soft, creamy coating called vernix starts to cover her skin, protecting it while she floats in amniotic fluid.

She's been busy. By around 18 weeks her ears stand out and she might begin to hear sounds, which means your voice may be part of her world. At 18 weeks she's about 5½ inches from crown to rump and about 7 ounces. By 20 weeks she's about 6⅓ inches and 11 ounces, and she's regularly sleeping and waking. Noises or your own movements might even wake her.

Go ahead and talk to her. Sing in the car. She may be listening.

Hello, on the screen

Somewhere around 18 to 22 weeks, you'll likely have your anatomy scan, often called the 20 week ultrasound. Plan on about 45 minutes, usually as its own visit.

The technician moves a wand over your belly, and there she is on the screen: her profile, her spine like a little string of pearls, her hands, her heart. The scan looks closely at her heart, brain, spine, kidneys, limbs, fingers and toes, face and more, records her heart rate, and checks the placenta and amniotic fluid.

The technician is often quiet during the scan, and that's normal. Your doctor reviews the results afterward. Most moms leave with a few keepsake pictures, the first ones for the fridge.

Saying her name

For many families, this is when the name conversation gets serious. Lists on the fridge, names whispered at night, names tried out loud at dinner to hear how they sound with your last name.

There's no deadline and no wrong way to do it. Some parents know right away. Some meet their baby first and decide in the hospital. A few gentle ideas:

• Say it out loud. First, middle and last, the way you'll call it across a playground.
• Look for meaning. A grandparent, a place you love, a word that means something to you both.
• Keep it close, if you like. Some couples keep the name a secret until she arrives. It can be a lovely thing to share only with each other.

The nesting begins

Somewhere in the middle months, a lot of moms feel a happy urge to get ready. Folding tiny clothes. Clearing a corner of the bedroom. Washing the same little blankets twice just to hold them.

Let it be joyful, not a to-do list. You don't need a finished nursery or a perfect plan. A few small, satisfying steps are plenty:

• Make a soft spot. A chair by a window where you can rest, read and feel her move.
• Start a little journal. The date you felt the first flutter. What you were doing. What you thought.
• Pick one thing to enjoy. A walk, a nap, a favorite meal. This season is yours, too.

If you ever have questions about her movements, especially later in pregnancy as her pattern becomes familiar, your doctor or midwife is always glad to hear from you.

Halfway there, Mama. Put your hand on your belly tonight and say hello back.
